eng Abstract:
[eng][cze] We study the convergence of GMRES for linear algebraic systems with normal matrices. In particular, we explore the standard bound based on a min-max approximation problem on the discrete set of the matrix eigenvalues.Studujeme konvergenci metody GMRES pro lineární algebraické systémy s normálními maticemi. Konkrétněji, vyšetřujeme standardní odhad založený na min-max aproximačním problému na diskrétní množině vlastních čísel matice.
